What causes this issue?

In the "Assignment to Article Hierarchy" maintenance view, some of the

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you want to edit one of these locked nodes, you can use transaction S
M12 to view the lock entries. In the Table Name field, enter

contact that person. Do not delete the lock entry manually as this could
cause inconsistencies.
